Abstract:
The concept on which the invention is based relates to a method for connecting a diaphragm (7) to a housing (4) of a pressure or force sensor (1), wherein a measurement element (5) is attached in the housing (4), which measurement element (5) can capture a load acting from the outside onto the diaphragm (7) during the use of the finished sensor (1). A housing ring surface (6) of the housing (4) is situated opposite a diaphragm ring surface (10) of the diaphragm (7), for producing a connection (13, 14) between these surfaces (6, 10), which are subjected to compressive loading by the load during use of the sensor (1). According to the invention, first a first connection (13) is produced in an inner region between the housing ring surface (6) and the diaphragm ring surface (10) until these surfaces (6, 10) rest against each other radially outside said first connection, and then a second connection (14) is produced between the housing ring surface (6) and the diaphragm ring surface (10), which connects the housing (4) and the diaphragm (7) to one another radially outside the first connection (13) up to the shared outer edge (11). Here, a defined connection depth d of the entire double connection (13, 14) is maintained.
Abstract:
Die Erfindung betrifft ein Verfahren zur stoffschlüssigen Verbindung zweier Bauteile (2), insbesondere zweier rotierender Wellenteile (2), in einem Verbindungsbereich (8), wobei benachbart zum Verbindungsbereich (8) Anformungen (10) zur Manipulation der Oberflächengeometrie der Bauteile (2) positioniert werden, wobei die beiden Bauteile (2) miteinander verschweißt werden und wobei eine Wärmenachbehandlung zur gezielten Einbringung von Druckeigenspannungen, deren Verteilung durch die manipulierte Oberflächengeometrie mitbestimmt wird, durchgeführt wird.
Abstract:
The invention relates to an injector body which comprises a first injector body element (1) and a second injector body element (3). The first injector body element (1) is provided with a first injector needle recess (10) accommodating an injector needle (15) and a first guide area (8) for the injector needle (15). In a first process step, the first injector body element (1) is assembled with the second injector body element (3). Brazing solder having a working temperature in the range of the tempering temperature of the first injector body element (1) is supplied to an assembly area (5). Said assembly area (5) is defined between the second injector body element (3) and the first injector body element (1). The assembled first injector body element (1) and second injector body element (3) is subjected to tempering during which the tempering temperature of the first injector body element (1) is reached.
Abstract:
Valve needle for a fluid injection valve, fluid injection valve and method for manufacturing a valve needle Valve needle (20) for a fluid injection valve (10) is disclosed. It comprises a needle shaft (13) and a sealing ball (15) welded to a tip (17) of the needle shaft (13). The welded joint (19) between the sealing ball (15) and the needle shaft (13) comprises at least two separate weld seams (72, 74), which extend along the perimeter of the valve needle (20) in the form of a c-shaped arc. Further, a fluid injection valve and a method for manufacturing the valve needle are disclosed.
Abstract:
A corner fitting includes a sleeve body having a hollow inner space and configured to coaxially fit over a pipe member of a predetermined size. An edge of the sleeve body at a second distal end has a corner cut portion, a protruding tab, and two recesses, the protruding tab being diametrically opposed to the corner cut portion in the radial direction of the sleeve body, and the recesses being diametrically opposed to each other in the radial direction of the sleeve body. The corner cut portion is configured and shaped such that the sleeve body fits together with an identical sleeve body on the pipe member of the predetermined size with the corner cut portions of the two sleeve bodies contacting each other and with the pipe being nested between the protruding tabs of the second distal ends of the two sleeve bodies.
Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen eines Verbundbauteils (10) , insbesondere eines Gasturbinenverbundbauteils (10) , wobei das Verbundbauteil (10) einen ersten Bauteilabschnitt (11) aus einem Magnesiumbasiswerkstoff oder Aluminiumbasiswerkstoff und einen zweiten Bauteilabschnitt (13) aus einem hochfesten Werkstoff, insbesondere aus einem Eisen- oder Nickel- oder Titan- oder Kobaltbasiswerkstoff , aufweist.
